GRACO Diaphragm Pump Husky 716 3/4" 190148 189536 108839

Product Description:

GRACO pneumatic diaphragm pumps boast exceptional diaphragm performance, featuring a service life that is 1/3-1/2 longer than similar products from other manufacturers. Certain diaphragm models even offer a service life exceeding 30 million cycles, significantly reducing the frequency of equipment maintenance and cutting down on operational costs.

These pumps exhibit outstanding self-priming capabilities, with a large suction range of up to 7 meters without the need for additional water injection or diversion operations. They can initiate operations swiftly and draw liquids into the pump chamber for delivery promptly, making them particularly suitable for scenarios requiring frequent starting and stopping, effectively enhancing work efficiency.

Various material options are available for components in contact with liquids, including 316L stainless steel, aluminum alloy, polypropylene, conductive polypropylene, and polyvinylidene fluoride. The aluminum alloy material undergoes anodizing treatment on the surface, with the pressure chamber receiving an epoxy coating post-anodizing. The pump body's central shaft is constructed from stainless steel to ensure high corrosion resistance, enabling stable operation in harsh environments.

Featuring an oil-free air pressure chamber design, these pumps do not require lubrication when utilizing CDA-driven gas. The air pressure chamber has a simple structure with minimal parts and low reliance on seals. Maintenance work is reduced as no lubrication additives need to be introduced, thereby preventing potential failures arising from lubrication issues.

These pumps maintain stable operation in both low and high-pressure environments, as well as in slow and fast operational states, without any jamming issues. Leveraging patented air valves with high wear resistance and a unique three-way pilot valve reversing design, these pumps guarantee exceptional reliability across various applications, achieving a minimal failure rate and ensuring continuous production.

All components are replaceable without the need to access the liquid chamber, ensuring easy assembly of parts and straightforward machine repairs. The air chamber is positioned above, preventing liquid ingress and facilitating online maintenance, significantly reducing equipment downtime and enhancing operational efficiency.
